A kid with good form kicks a ball with a force of 10.0 N while making contact for 0.225 s. An adult with bad form kicks the ball with a force of 21.2 N while making contact for 0.102 s. What is the impulse, change of momentum, imparted by the adult?

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

explanation:

-reverse card

because growing process had stoped after 4-5 year

this would be about 43%
